Bonedigger. Please remember some of the following. First of all the usage of WD-40 or other such chemicals, used on numerous coins of different materials and different contamenates, anything can be the results. Many products such as WD-40 have manufacturing tolerances in their formulae. Also, they occationally change such formulae to comfuse the compitition. What you purchased yesterday may be different than what you purcahsed a week ago. This means that what MIGHT work with and for some may have horrible results for others. The type of contaminate on a coin can vary extensively and the addition of a solution of the wrong type can ruin a coin further. Many blurt out names such as PVC or Vertigris without knowing what the substance may in reality be composed of. The point it if you do not know what the contaminate on a coin is, do not know the exact formulae of a solution, don't allow experiment with a valuable coin.
Next when anyone on the internet tells me they did this or that and it came out perfect, I always remember an old saying. Believe nothing of what you hear and half of what you see.
